fmtools use VIDIOCSTUNER, with, in turn, calls VIDIOC_S_INPUT on v4l1-compat.
So, those ioctls are required for V4L1 to work properly.

Before this patch, vivi were simulating a scatter gather DMA transfer.
While this is academic, showing how stuff really works on a real PCI
device, this means a non-optimized code.
There are only two memory models that vivi implements:
1) kernel alloced memory. This is also used by read() method.
On this case, a vmalloc32 buffer is allocated at kernel;
2) userspace allocated memory. This is used by most userspace apps.
video-buf will store this pointer.
a simple copy_to_user is enough to transfer data.
The third memory model scenario supported by video-buf is overlay mode.
This model is not implemented on vivi and unlikely to be implemented on
newer drivers, since now, most userspace apps do some post-processing
(like de-interlacing).
After this patch, some cleanups may be done at video-buf.c to avoid
allocating pages, when the driver doesn't need a PCI buffer. This is the
case of vivi and usb drivers.

The direct register access ioctls were defined as kernel internal only,
but they are very useful for debugging hardware from userspace and are
used as such. Officially export them.
VIDIOC_INT_[SG]_REGISTER is renamed to VIDIOC_DBG_[SG]_REGISTER
Definition of ioctl and struct v4l2_register is moved from v4l2-common.h
to videodev2.h.
Types used in struct v4l2_register are changed to the userspace
exportable versions (u32 -> __u32, etc).
Use of VIDIOC_DBG_S_REGISTER requires CAP_SYS_ADMIN permission, so move
the check into the video_ioctl2() dispatcher so it doesn't need to be
duplicated in each driver's call-back function. CAP_SYS_ADMIN check is
added to pvrusb2 (which doesn't use video_ioctl2).

Currently, the driver works in bulk mode supporting both USB 2.0 and
1.0 with and without hardware pid filters.
The ULi m9205 also supports isochronous transfer mode, but I have
dropped support for it because it depends on firmware and does not work
on all USB host chips. Further, I have no firmware with remote

I noticed that udev does not create a symlink for the CinergyT2 remote input
device in /dev/input/by-id, which is required if I want to have a
unique device name for lircd.
The attached patch tries to achive this. However, udev still omits the
input device for /dev/input/by-id symlinks. I think something is still
not reported correctly.

v4l2_tvnorm were meant to describe video standards and its names to V4L2 API.
However, this were doing by some static structures at the driver.
This patch changes the internals in a way that, at the driver, only a
v4l2_tvnorm (a 64 bit integer) should be filled, with all supported
tvnorms. videodev will dynamically generate the proper API array
based on supported standards.

video_ioctl2 handler provides V4L2 API parsing.
Using it makes the driver simpler, and isolates API parsing.
This allows future reusage of driver controls using other ways, like sysfs
and/or procfs and increases isolation of driver-specific handling from the
generic common ioctl processing.

With the previous patch, mplayer started but was polling the video
device forever without any video actually coming out. Further analysis
showed that it does a VIDIOC_S_FMT with width and height set to -1 (!!!).
The code handling this only cares that both are lower than the minimum
range allowed so it ends up setting the size to 19x17 (!!) This pretty
much breaks the encoder here. Even if this breakage is yet another (TM)
result of my setup, setting the size to 19x17 by default would surprise
most users IMHO.
So, special case for -1 and interpret this to be a request for the
default size, please. Users can then set their favorite size both
through mplayer and through sysfs.
With this patch, mplayer finally works in pvr:// mode (not that we
really gain anything over operating it through sysfs with lirc,
sometime I might actually get off my lazy a** and contribute this
setup too)

Audio mode changes are not private to the audio chip - other I2C
modules need to see this as well. And since the command in question
is VIDIOC_S_TUNER which is a standard v4l2 command, we really should
be broadcasting it out. This change sets up a broadcast pathway for
VIDIOC_S_TUNER and also eliminates the now redundant code from the
audio chip handler.
This fix enables stereo reception for the FM radio
